The actuator 26 may engage any one of the plurality of detents 24 defined along the first and second side 162, 164 of the actuation feature 22 as the knob 34 translates the actuator 26 within the actuation feature 22.

With further reference to FIGS. 11-16 , the actuator 26, as mentioned above, includes the first engagement member 28 and the second engagement member 30 operably coupled to a lower portion 180 of the actuator 26. The actuator 26 also includes a protuberance 182 outwardly extending from a side portion 184 of the actuator 26, which is configured to engage at least one of the detents 24. It is generally contemplated that the protuberance 182 may extend from a first side portion 186 and a second side portion 188 of the actuator 26, such that the protuberances 182 may engage and be operably coupled with the detents 24 defined along the first side 162 and the second side 164 of the actuation feature 22, respectively. As illustrated in FIGS. 15 and 16 , the protuberance 182 is generally positioned beneath the receiving aperture 168 defined by the actuator 26 to generally align and correspond with the detents 24.

As illustrated in FIG. 15 , the first and second engagement features 28, 30 of the actuator 26 each include a first prong 190 and a second prong 192. It is generally contemplated that the first and second prongs 190, 192 of each of the first and second engagement features 28, 30 define a gap 194 therebetween. The first and second prongs 190, 192 of are configured to engage and be communicatively coupled with the controller 62. Additionally or alternatively and as illustrated in FIG. 16 , it is also contemplated that the first engagement member 28 and the second engagement member 30 of the actuator 26 may each have a first surface 196 and a second surface 198. It is generally contemplated that the first surface 196 of each of the first and second engagement members 28, 30 is recessed relative to the second surface 198.

The printed circuit board 64 is configured to translate inputs received from the actuator 26 via the first and second engagement features 28, 30 to execute an operation of the countertop appliance 10. For example, the first and second engagement features 28, 30 may be translated along the printed circuit board 64 via translation of the actuator 26 via the knob 34 of the slider 32. The translation of the actuator 26 along the printed circuit board 64 may correspond with an alteration of a speed function of the countertop appliance 10.

For example, the engagement of various portions of the printed circuit board 64 via the first and second engagement features 28, 30 may correspond to varying speeds of the countertop appliance 10 as set forth in an algorithm of the controller 62. The controller 62 may receive the inputs from the printed circuit board 64 as a result of the communication with the first and second engagement features 28, 30, and the controller 62 may alter the speed or other function of the countertop appliance 10. The engagement of the protuberance 182 of the actuator 26 with the detents 24 defined by the actuation feature 22 provide tactile feedback for the user during translation of the knob 34. The knob 34 translates the first and second engagement features 28, 30 along the printed circuit board 64 via the actuator 26, and the user can detect the adjustment via the engagement between the protuberance 182 and the detents 24.

Referring again to FIGS. 1-16 , the adjustment assembly 20 of the countertop appliance 10 is configured to minimize the potential access and build-up of food particles within the mechanical compartment 56 of the countertop appliance 10. The barrier member 36 cooperates with the slider 32 and the bracket 90 to block and generally obstruct the slot 18 defined by the mixer head 16 and the opening 94 defined by the bracket 90. The engagement of the barrier member 36 with the retention features 104 of the bracket 90 assist in maintaining the position of the barrier member 36 relative to the opening 94 defined by the bracket 90. Further, the barrier member 36 being operably coupled within the groove 126 defined by the slider 32 and the selective engagement with the notch 128 defined within the groove 126 via the projection 150 of the barrier member 36 assists in proper alignment and cooperative movement of both the slider 32 and the barrier member 36. This cooperative movement and translation of each of the slider 32 and the barrier member 36 further maintains the obstruction of the opening 94 in the first position 130 and in each of the plurality of second positions 132 of the slider 32 and the barrier member 36. In addition, the ledge 144 defined by the slider 32 further assists in minimizing access of food particles into the mechanical compartment 56 in particular relative to the actuation feature 22.

It is also contemplated that the uniform detents 24 defined along the length L₂ of the actuation feature 22 assists the user in detecting the varying speed selections of the countertop appliance 10 by easily manipulating and translating the knob 34, such that the protuberance 182 of the actuator 26 may engage each detent 24 with minimal disruption. The uniform shapes and size of the detents 24 minimizes the precise translation of the knob 34 that may be otherwise utilized to select a function of the countertop appliance 10 where the detents 24 are not uniform in size. The uniform size and configuration of the detents 24 maximizes the user proficiency and operation of the countertop appliance 10.

Referring still to FIGS. 1-16 , the configuration of the first and second engagement features 28, 30 further maximizes the operation of the countertop appliance 10 by minimizing the potential for food particle build-up on either of the first and second engagement features 28, 30. For example, in either configuration, the first and second engagement features 28, 30 define either the gap 194 defined between the first and second prongs 190, 192 and/or the aperture 200 centrally defined on each of the first and second engagement features 28, 30. In either configuration, the minimal buildup of food particles assists and improves the overall communication and efficiency between the actuator 26 and the controller 62 via the printed circuit board 64.
